Most people have bought something online they later questioned. A gadget. A piece of furniture. Maybe even a car. But in 1999, Mark Cuban took online shopping to a level that has never been matched. The billionaire entrepreneur purchased a Gulfstream V private jet online for $40 million, earning a Guinness World Record for the largest single e-commerce transaction ever made.
More than 25 years later, the record still stands.
A $40 Million Purchase With a Few Emails
Cuban has shared the story several times over the years, including in a 2010 interview with Business Jet Traveler. After researching the aircraft on Gulfstream’s website, he asked his pilot to test it out.
Don’t Miss:
“He raved about it,” Cuban said.
The next step was surprisingly simple. “So I sent another e-mail saying I wanted to buy it,” he said. “I got the banking instructions, wired the money and that was it.”
The purchase came shortly after Cuban became one of the biggest winners of the dot-com era. His company Broadcast.com was sold to Yahoo for $5.7 billion, giving him the financial freedom he had spent years pursuing.
One of the most important lessons he learned came from his father.
“The one most valuable asset you don’t own is your time,” Cuban told “Shark Tank” investor Barbara Corcoran in 2020.
That philosophy helps explain why he was willing to spend so much money on a private jet. For Cuban, it wasn’t just about luxury. It was about saving time, increasing flexibility and making it easier to balance work and family life.
The Real Reason He Bought Such a Big Plane
When Corcoran asked why he bought such a large aircraft, Cuban’s first answer was refreshingly honest.
“Because I could.”
But there was more to it than that.
Cuban recalled that when he was 16, his father bought him inexpensive “beater” cars. While many teenagers dreamed about sports cars, Cuban preferred a station wagon because he could fit all his friends inside and drive them to basketball games.
“I wanted the station wagon because I could take all my buddies to go play basketball,” he said.
That same mindset carried over to the jet purchase. As Cuban put it, “It’s not even bigger is better. It’s just like, okay, what can I have the most fun with?”
The story also highlights a theme that has defined much of Cuban’s career. While many entrepreneurs chase the latest trend, Cuban often built businesses that supplied the tools behind those trends. Instead of joining the gold rush, he frequently found ways to sell the shovels. Broadcast.com helped power the early internet boom without needing to become the next media giant itself.

For most Americans, a $40 million private jet isn’t exactly relatable. Millions can’t afford a $1,000 emergency expense. But Cuban’s story offers a reminder that the biggest opportunities often come from identifying where value is being created and finding ways to support that growth.
Mode Mobile is built around a similar idea. Instead of creating another side hustle that demands more hours, the company developed EarnPhone, a smartphone that allows users to earn rewards for activities many people already do every day, including reading news, listening to music and playing games.
Mode Mobile is currently allowing investors to participate in its pre-IPO offering. Now, you can invest for just $0.52 per share with a $1,300 minimum.

Building Wealth Across More Than Just the Market
Building a resilient portfolio means thinking beyond a single asset or market trend. Economic cycles shift, sectors rise and fall, and no one investment performs well in every environment. That’s why many investors look to diversify with platforms that provide access to real estate, fixed-income opportunities, precious metals, and even self-directed retirement accounts. By spreading exposure across multiple asset classes, it becomes easier to manage risk, capture steady returns, and create long-term wealth that isn’t tied to the fortunes of just one company or industry.
